VALVE FOR RADIATORS.

Specification of Letters Patent.

atented Sept. 12, 1905.

Application filed December 17,1904. Serial No. 237,191.

Be it known that I, JOSEPH F. \VINKLER. a citizen of the United States,residing in the city and county of Philadclphia,State of Pennsylvania,have invented a new and useful Valve for Radiators, of which thefollowing is a specitication.

My invention consists of a novel construction of a radiator-valve whichpermits the air in the radiator to escape, but which automaticallycloses when steam from the radiator enters the valve.

It also consists of means for preventing water from escaping through thevalve.

It further consists of novel features of construction, all as will behereinafter set forth.

There has been up to the present time considerable trouble and annoyancein valves of this class on account of the water and steam which escapetherethrough. the effect of which is evident.

Figure 1 represents a sectional view of an automatic valve embodying myinvention properly secured to one of the sections of a radiator, aportion of two of which are shown. Fig. 2 represents a transversesectional view on line .0 :1, Fig. 1. Fig. 3 represents a transversesectional view on line i y, Fig. 1, showing the valve open. Fig. 4represents a similar view to Fig. 3, but the parts in differentposition.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates the top portion of two of thecolumns of a radiator, to the outer one of which is secured at a properpoint a duct 2, extending in the present instance outwardly and upwardlyand having its end 3 adapted to receive a cylindrical casing 4, one endof which is closed by a nut or cap 5, having threaded engagement withthe same and which may be bent outwardly to form at a point 6 a hollowor cup, the use of which will be hereinafter explained. The other end ofthe casing l is closed, but has a tube 7 extending therethrough'andhaving threaded engagement therewith, a shoulder 8 on the tube formingan air-tight joint with the inner walls of the casing at. The tube 7 hasa port 9 opening into the interior of the casing at, said port beingcontrolled by a cylindrical valve 10, closely titted within the tube 7and provided with a port 11, arranged to normally register with the port9.

12 designates the head or cover of the valve 10, which is held in airtight engagement with the end of the tube 7 by means of a spring 13,sliding on a pin l i. which is secured to a lever-arm 15. the latterbeing attached to the head 12. The cup 6 in the cap 5 receives the pin14 and prevents the spring 13 from leaving the said pin 14. The lever 15has pivoted at its end 16 a lever-arm 17, which latter is secured to acoiled tube 18. which extends through the closed wall 19 of the casing Land through the duct 2 and may extend into the column 1, to which theduct 2 is attached. The ends of the tube 18 are closed in any suitablemanner--for example, by a screw-plug or equivalent devicc and the tubeis filled with a liquid or substance which quickly expands on beingheated. Inserted in the closed wall 19 and having threaded engagementtherewith is a valve-casing 20, 1 aving a port 21, which is adapted tobe closed by a ball-valve 22, the end of the chamber 20 near the port 21being rounded, so as to form a seat for the said valve 22, which isprevented from falling through the open end 23 of the valve-casing 20 bya pin 24:, extending through the walls thereof.

The operation is as follows: \Vhen it is desired to admit steam to theradiator and the suitable valve therefor is opened, the steam enteringthe radiator will force the air contained in the radiator before it,which will escape through the duct 2, port 21, port 9, port 11, and tube'7. \Vhen a certain predetermined amount of heat comes in contact withthe coil 18, the said heat will cause the highly sensitive materialwithin the tube to expand, which will cause the coiled tube 18 to bendoutwardly and operate the lovers 17 and 15 to the position as shown indotted lines in Fig. 2. This will cause the head 12 and the cylindricalvalve 10 integral therewith to turn, and thus bring the port 11 out ofregister with the port 9 and prevent the escape of steam theretiirough.If the water should at any time rise in the columns 1 above the level ofthe normal position of the valve, the latter will be carried upward bythe water, closing the port 21 and preventing any escaping through thevalve. It will be evident that when the steam is shut off the substancein the tube 18 will cool off and cause the coil 18 to contract, drawingwith it the levers 17 and 15, and thus causing the valve 10, to the head12 of which the lever 15 is secured, to turn and bring the port 11 innormal register with the port 9, which will allow the air to escapethrough the tube 7. The latter is shown thread- ITO ed at its end inorder that the same may be connected with a suction-pump when it isdesired to draw from the radiator the foul air therein. By reason of theheat in the radiator when the supply is shut 01f the valve will remainclosed for some time, thus preventing the cool atmospheric air fromentering the radiator, which will cause the latterto retain its heat amuch longer time. In all the forms of radiator-valves now on the marketwhen the steam-supply is shut off the cool air at once enters theradiator, and the same will be quickly cooled.

It is obvious that by the employment of'my device a great economy in theuse of the steam is brought about.

It will be evident that various changes may be made by those skilled inthe art which may come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of the character described, a casing, a tube extendingtherein and having engagement therewith, ashoulder on said tube formingan air-tight joint with the inner walls of said casing, a port throughsaid tube, a

valve adapted to fit within said tube and to control said port, a headfor said valve, aspring interposed between said casing and said head andadapted to retain the latter in air-tight engagement with the end ofsaid tube, said valve being actuated by heat, an inner valvecasing and aball-valve therein actuated by water.

2. In a device of the character described, a casing, atube' extendingtherein and having threaded engagement therewith, a shoulder on saidtube forming an air-tight joint with the inner walls of said casing, aport through said tube, a valve adapted to fit within said tube and tocontrol said port, a head for said valve, a recess at'the rear'of saidcasing, a pin located in said recess, a spring mounted on said pinengaging said head and adapted to retain the latter in air-tightengagement with the end of said tube, said valve being actuated by heat,an inner valve-casing, and a ballvalve therein adapted to be actuated bywater.
